You have 1 copy of AV_business licensed for lets say 15 users with one 
expiry date. However you could purchase another copy for say 5 users 
with a different expiry date.

Also you can purchase across the range, Home, Business, Linux or Windows.

Yeah as I say the db and tables are created now my plan for today is 
linking (joining) the tables then having a play. Given that I'm learning 
deleting, updating blah blah blah is all good learning stuff repetition 
is a good tool for learning.

It is using InnoDB actually I used the workbench more for giving me a 
graphical representation of what I've done so far rather than using it 
to 'create' which is what I imagine it can do.
